If g(x) is obtained by shifting f(x) down by 7 units, the value of k is 7.

In Mathematics, the translation of a geometric figure or graph downward simply means subtracting a digit from the value on the y-coordinate (y-axis) of the pre-image or function.

Mathematically, a horizontal translation to the left is modeled by this mathematical expression g(x) = f(x + k) while a vertical translation to the negative y-direction (downward) is modeled by this mathematical expression g(x) = f(x) - k.

Where:

By comparison based on the graph of f(x) = (0.5)^x and g(x) = (0.5)^x − k, we can logically deduce that the value of k is equal to 7.

The given equation is of form : x1+x2+...+xn = k, where x1>=m1, x2>=m2 and so on, this is typical equation which can be mapped to questions like :

Q)You have n candies and you want to distribute it to k children where each child gets at least m candies or in other words n same candies in k different boxes, where each box must have certain number of candies.

In your case m1=m2=...=mn= 0(or 1 based on your definition of natural numbers, lets first solve for condition where lower bound is 0).

This solution is simple, (n-1+k C k) which gives (3-1+11 C 11) = 78 as answer.

Now, the case for which we start natural numbers with 1 :

First we need to reduce it to previous formula. This can be done by making the lower bounds as 0 or to say lets first distribute minimum number of candies to children.Now we are left with k-m1-m2...-mn candies, so equation reduces to :

x1+x2+...+xn = k-m1-m2...-mn

or in your case x1+x2+x3 = (11-3) = 8

Now, using the previous formula (3-1+8 C 8) = 45.Which is required solution.

A linear equation in two variables is an equation of the form ax + by + c = 0 where a, b, c ∈ R, a, and b ≠ 0. When we consider a system of linear equations, we can find the number of solutions by comparing the coefficients of the variables of the equations. Also, we can find the number of solutions by the graphical method.

Consider the pair of linear equations in two variables x and y.

a1x + b1y + c1 = 0

a2x + b2y + c2 = 0

Here a1, b1, c1, a2, b2, c2 are all real numbers.

Note that, a12 + b12 ≠ 0, a22 + b22 ≠ 0

1. If (a1/a2) ≠ (b1/b2), then there will be a unique solution. If we plot the graph, the lines will intersect. This type of equation is called a consistent pair of linear equations.

2. If (a1/a2) = (b1/b2) = (c1/c2), then there will be infinitely many solutions. The lines will coincide. This type of equation is called a dependent pair of linear equations in two variables

3. If (a1/a2) = (b1/b2) ≠ (c1/c2), then there will be no solution. If we plot the graph, the lines will be parallel. This type of equation is called an inconsistent pair of linear equations.

Answer:

The dimensions of the rectangle are 22 and 55 feet

Step-by-step explanation:

We can set the Width to be X and the Length to be 3x-11 since it is 11 less than 3 times the width.

the perimeter is 2 widths plus 2 lengths so x + x + 3x-11 + 3x-11 or 8x -22
since the perimeter is also 154, we get that 8x-22 = 154, we can add 22 to both sides and get that 8x = 176 if we divide both sides by 8 we get that X or the width is 22 and since the length is 3 times the width minus 11 it is

When we compare the given expression with the slope-intercept form, we get the required slope. Here, the slope is -3.

A line's slope or gradient numerically expresses its steepness and direction. It provides the ratio of how much y alters when x alters by a particular amount. Since m is the slope and c is the y-intercept, y=mx+c is the general form. This is the slope-intercept form.

Compare the given expression y=-3x-7 with the slope-intercept form. We get, the slope value as m=-3 and the intercept value as c=-7. Therefore, the required answer is -3. So the value of y changes with -3 times of x.

Answer:

In standard position, the terminal ray of angle A passes through the point (10,-4) on the coordinate plane. The distance of the point (10, -4) from the origin (0,0) is the hypotenuse of a right triangle. The horizontal distance of the point from the y-axis is the x-coordinate, which is 10, and the vertical distance of the point from the x-axis is the y-coordinate, which is -4.

The secant of an angle is the ratio of the hypotenuse (c) to the adjacent side (a). In this case, the hypotenuse is the distance between the point (10, -4) and the origin (0,0) and the adjacent side is the x-coordinate which is 10.

So sec(A) = c/a = √(10² + (-4)²)/10 = √(100+16)/10 = √116/10 = √29/5

So sec(A) = √29/5 which is the simplified form.

here s = 36 , then

A = [tex]\frac{36^2\sqrt{3} }{4}[/tex] = [tex]\frac{1296\sqrt{3} }{4}[/tex] = 324[tex]\sqrt{3}[/tex] ≈ 561.2 yd²

Note that in the above problem,  m∠Y > 72°. This problem can be approached with logic and Physics. (Option A)

Usually, you would require at least two sides to solve for an angle. However, without out that information lets examine what we know.

1) It is given that in Δ UVW, the side opposite UW is 36cm;

2) we know that in ΔXYZ the side opposite XZ is 39cm.

3) we know that both triangles are similar in that they are scalene triangles

4) we know that they have similar sides that is:

UV ≅ XY; and

VW ≅ YZ

5) ∠V = 72°

Given item 4, since all other factors between both triangles are similar, the logic of physics suggests that extending XZ will increase ∠Y and vice versa.

Since we know that XZ is 39cm (that is 3cm longer than UW), it therefore is logical to expect m∠Y to be larger than the angle to which it is similar in  ΔUVW which is ∠V.

Thus, the correct answer is m∠Y> 72° (Option A)

(5x-3)(5x-3) is a product of two binomials, which can be expanded using the distributive property.

What is an example of distributive property?

A value is multiplied by a sum to leverage the distributive property of multiplication over addition. Take the case where you want to multiply 5 by the sum of 10 + 3. We frequently add the two sums when two terms are similar instead of multiplying by 5. However, the attribute states that you must first raise each addend by 5..

To expand, you would multiply each term in the first binomial (5x-3) by each term in the second binomial (5x-3) and then add the products.

(5x-3)(5x-3) = (5x)(5x) + (5x)(-3) + (-3)(5x) + (-3)(-3)

84 goes to 91 by adding 7 and if added 7 again, U will get 98.

The speed of the car is 100 kilometers per hour, since it traveled 200 kilometers in 2 hours.

Speed = Distance/Time

Speed = 200 kilometers/2 hours

Speed = 100 kilometers/hour

The speed of a car is determined by dividing the distance traveled by the amount of time it took to travel that distance. In this case, the car traveled 200 kilometers in 2 hours. To calculate the speed of the car, we divide the distance (200 kilometers) by the time (2 hours). This gives us 100 kilometers per hour, which is the speed of the car. In other words, the car traveled 100 kilometers in 1 hour.

The speed of a car is an important factor in determining how fast a car can go. It is also important to consider other factors such as the weight of the car, the type of fuel it uses, and the road conditions. All of these factors can affect the speed of the car and should be taken into account when calculating the speed of a car.

It is clear that planes q and r are parallel based on the fact that they do not intersect and remain in the same plane.

Lines a and b, however, are skew because they are not parallel, not in the same plane, and do not intersect.

This can be seen by looking at the angles formed by lines a and b, as they are not equal and are not of the same degree.

Furthermore, lines a and b cannot be in the same plane as planes q and r, as they do not intersect, and therefore they must be skew.
